I think it's funny how people are saying this sounds like "old" In Flames, just because it has a few acoustic-ish parts.
My review of the album is this: Aside from a few very standout tracks, this album is very thin, shallow, and takes In Flames back a thousand steps in terms of being an outstanding band. The leaked tracks - Deliver Us, Sounds, A New Dawn - each of these tracks spell out classic In Flames that we've come to expect; catchy choruses, layered songwriting, energy, dedication.
But the other tracks? Almost every single one of them falls way too short of these above tracks (which will most likely be the singles). The Puzzle and Darker Times are messy "nu-metal" tracks that hark back more to the songwriting style of Coal Chamber or Korn, without being as catchy - you'd at least expect In Flames to throw a charming chorus in there, or some layered keys, but it just doesn't happen.
Moving on to the two experimental songs, The Attic and Jesper's Door, these tracks are nothing, absolutely nothing, but a few spoken words by Anders (no "surprise energy" like the end of Bedtime Story or Evil In A Closet) and tweaks and toots. Not really even any melody, though the guitars on The Attic are very soothing.
Next, to Dead Ships and Fear Is The Weakness, these two tracks try to emulate the formula and mood that Deliver Us, New Dawn, and Sounds had set up - an energetic verse-chorus with keys and a few guitar experiments. However, the level falls extremely short of "singles", lacking originality and attention. Although many songs on Sense Of Purpose sounded alike, the "less good than the other" was not once a problem on that particular release. Opposite to Sounds, every song on Purpose had it's own merit and energy.
Now, to Ropes and Enter Tragedy - Ropes is a surprising return to a slightly complex Gothenburg style a bit more nodding to Soilwork, with some blazing guitars to be found, and you really ride on this track until the chorus hits - the chorus just, like most of the tracks on this release, is completely uninteresting, no hooks or things to grasp onto. It's almost like Anders gave up on writing a good chorus as so many people bag on his very good talents. (And no, the catchy chorus was not replaced with brutality here - just replaced with a bad chorus.) Enter Tragedy is also a nu-metalish track that drones along and does nothing interesting.
Lastly, Liberation is probably the best song on the album next to the three kings. This song shows the experimentation, layered music, catchy songwriting, and depth that In Flames are capable of, and the only sad thing is that the song is not very long and still does not pack the energy I'd expect.
Overall, the album sucks IMO, and most of the songs drone on and on. While I hold no band to a certain sound, I've said before that I 100% expect good, interesting songwriting, and this release has almost none of that. Experimentation should evoke emotion. Energy should evoke hooks. This album does not do that, nor does it really any more experiments than Sense or Come Clarity, and actually has less - I personally miss the acoustic songs to be honest, like Pessimist, Come Clarity, ect etc and I was really hoping for one!
